Sewer rehabilitation

The City Côte Saint-Luc is rehabilitating the sewer main on many streets across the city in 2018. If you live at a home where your connection to the sewer network will be temporarily sealed, you will receive a door hanger with information.

If you live at a home where your connection to the sewer network wil not be affected, but where you may hear noise and smell odours, you will receive a letter with information.

REHABILITATION OF SEWER BY LINING
Rehabilitation by lining is a trenchless technology which consists of inserting a liner into the sewer main to render it structural and watertight.

TEMPORARY INTERRUPTION OF MUNICIPAL SEWER SERVICE
To carry out a sewer rehabilitation by lining, the house drains connecting to the sewer main must be temporarily sealed for several hours. Although the water supply will not be affected, we ask that you avoid discharging water into your drain (e.g., do not flush the toilet water, do not run the washing machine, etc.) to reduce the risk of sewer back-up. A door hanger will be distributed by the city contractor to all affected residents, 24 hours before the start of work, to confirm the date, time and exact duration of the interruption.

NOISE
Since the time required to rehabilitate a pipe depends on the pipe diameter, length and the number of services to be connected to the sewer main, noise may be occasionally caused by the equipment late at night.

TRAFFIC AND PARKING
During the work, traffic and parking restrictions may be applied in the area. At all times, pedestrian access to the homes and establishments will be preserved.

ODOURS
Odours resulting from the resin used to line the sewer may be noticeable during the work. Although this odour may be noticeable at very low levels, it presents no risk to human health. In order to mitigate this normal occurrence, if your residence is in the work area, please follow the steps as indicated in the diagrams below. It is recommended that residents locate all drains and ensure that the building’s plumbing is in good condition.

Floor drains are designed to maintain a seal in the pipe to prevent all gases and odours entering your home.

During the construction period, make sure to pour at least a liter of water in each of your floor drains (basement) and in all sinks and shower drains in your home or apartment.
